<p>When a <a class="link" href="GFile.html" title="GFile"><span class="type">GFile</span></a> is requested with an URI containing <em class="parameter"><code>scheme</code></em>
 (e.g. through
<a class="link" href="GFile.html#g-file-new-for-uri" title="g_file_new_for_uri ()"><code class="function">g_file_new_for_uri()</code></a>), <em class="parameter"><code>uri_func</code></em>
 will be called to allow a custom
constructor. The implementation of <em class="parameter"><code>uri_func</code></em>
 should not be blocking, and
must not call <a class="link" href="GVfs.html#g-vfs-register-uri-scheme" title="g_vfs_register_uri_scheme ()"><code class="function">g_vfs_register_uri_scheme()</code></a> or <a class="link" href="GVfs.html#g-vfs-unregister-uri-scheme" title="g_vfs_unregister_uri_scheme ()"><code class="function">g_vfs_unregister_uri_scheme()</code></a>.</p>
<p>When <a class="link" href="GFile.html#g-file-parse-name" title="g_file_parse_name ()"><code class="function">g_file_parse_name()</code></a> is called with a parse name obtained from such file,
<em class="parameter"><code>parse_name_func</code></em>
 will be called to allow the <a class="link" href="GFile.html" title="GFile"><span class="type">GFile</span></a> to be created again. In
that case, it's responsibility of <em class="parameter"><code>parse_name_func</code></em>
 to make sure the parse
name matches what the custom <a class="link" href="GFile.html" title="GFile"><span class="type">GFile</span></a> implementation returned when
<a class="link" href="GFile.html#g-file-get-parse-name" title="g_file_get_parse_name ()"><code class="function">g_file_get_parse_name()</code></a> was previously called. The implementation of
<em class="parameter"><code>parse_name_func</code></em>
 should not be blocking, and must not call
<a class="link" href="GVfs.html#g-vfs-register-uri-scheme" title="g_vfs_register_uri_scheme ()"><code class="function">g_vfs_register_uri_scheme()</code></a> or <a class="link" href="GVfs.html#g-vfs-unregister-uri-scheme" title="g_vfs_unregister_uri_scheme ()"><code class="function">g_vfs_unregister_uri_scheme()</code></a>.</p>
<p>It's an error to call this function twice with the same scheme. To unregister
a custom URI scheme, use <a class="link" href="GVfs.html#g-vfs-unregister-uri-scheme" title="g_vfs_unregister_uri_scheme ()"><code class="function">g_vfs_unregister_uri_scheme()</code></a>.</p>
